Data Exploration: IUCN and AquaMaps

(4) Looking at the percent of smaller species range that is within the larger range.

For each range

Plotting species from q1 (well-matched)

Plotting species from q2 (distribution-matched) ***

Global representation of species

By counting the number of unique species are found in each of the half degree cells we can then create a single global raster of number of species.

Now look at all aquamaps species

Plotting species from q3 (area-matched)

Plotting species from q4 (poorly matched)

Changes in SPP for scenarios

Comparing three scenarios to the current (v2015) global model for SPP:

• Baseline is: preferring IUCN rangemaps over Aquamaps rangemaps; Aquamaps ‘presence’ threshold is set at 40% or greater.
• Scenario 1: preferring IUCN rangemaps over Aquamaps; AM presence threshold set at >= 1% (effectively, all occurrences).
• Scenario 2: preferring AM maps over IUCN; AM presence >= 40%.
• Scenario 3: preferring AM over IUCN; AM presence >= 1%.
